What is 20.5 as a Fraction?
Answer
The answer for 20.5 as a fraction will be 41/2.
Explanation
Converting a decimal to a fraction is a task for students that can be done easily. You can follow the steps mentioned below to find the answer.
Step 1: Firstly, any decimal number should be converted to a fraction for easy calculation. Here, 20.5 is the number on the numerator and the base number 1 will be the denominator. Then, 20.5 becomes 20.5/1.

Step 3: Here 5 is the GCD of 205 and 10. Now, to make the fraction simpler, divide the numerator and denominator by 5. 205/10 = 41/2 Hence, 20.5 is in the form of a fraction of 41/2.
Thus, 20.5 can be written as a fraction 41/2.
